COKlNG-RECEPTACLE.

Specification of Letters Patent.

Patented A-ug. 28, 1906.

Application filed November 16, 1906. Serial No 287,898.

To all whom, it may concern.-

Be it known that we, HORACE J. WICKYIAM, residing at Manchester, WILBUR L. SHEPARD, residing at Ehnwood, and FREDERICK ROCKWELL, residing at West Hartford, in the county of Hartford and State of Connecticut, citizens of the United States, have invented a new'and useful Coking-Receptacle, of which the following is a specification.

This invention relates to a receptacle which is desigrlied to receive and to hold blocks of peat w 'le being baked and transformed into co e.

The object of the invention is to provide a receptacle which is simple to construct, eas to handle, and ellicient in action, which will hold a large quantity of peat, and which is easily sealed, so that gases evolved by the action of coking can escape and relieve the interior pressure and be utilized for facilitat-.

ing the process, but flames or gases of combustion cannot enter the receptacle.

Figure 1 of the accompanying drawings shows a central vertical section oi a receptacle which embodies the invention. Fig. 2 shows a horizontal section on the plane indicated by the line 2 2 on Fig. 1. f

The chamber 1 which is shown is preferably formed of cast-iron having a cylindrical cross-section. Extending down from the top of this chamber is a flue :2, which is preterably .locatcd centrally and is circular in cross-section. The flue extends from top to bottom and is open at both ends, but the top of the chamber 3 is tightly closed, except for the flue-opening, so that no gases can csca )e from the interior. The lower edge of the chamber about the open end is preferably notched.

The base 4, which may be formed of cast iron, is a little larger in diameter than the exterior diameter of the chamber. Extending upwardly about the periphery of the base is a flange 5. Extending upwardly at the center 01'' the base is a hubG. This hub is sonnvwhat smaller in diameter than the interior diameter of the llue through the chamber. There is no opening through the bottom oi" the base except through the hub. The bottom of the base may be recessed, as at 7. If the bottom is recessed, as shown, two circular troughs are formed, the. outer oi'- which is of sullicicnt size to receive the lower edge of the chamber and the, inner of which is of sutlicient size to receive the lower edge of the 'flue through the chamber. These troughs contain a granularsubstance, such as sand, and after the chamber has been filled with blocks of dried peat its lower edge is worked down into the granular material, so that this material will pack the joint between the lower edge of the chamber and lower edge of the flue and the bottom of the base.

Peat which has been pressed into blocks of the desired sha )e and size are laced in the chamber, and a ter it has beenfil ed the chamber, it the top is not removable, is turned over and its lower edge worked down into the granular material in the base. A screen or grate 8 may be secured in the chamber near the open end to prevent the blocks from fall.- ing out when the receptacle is turned over. In practice a number of these rece tacles after being filled with peat are move into a furnace and subjected to the action of a hot iirc. The heat from the fire asses up around the outsides and through t e fines, and the gases which are generated in the interior are expelled through the granular material and rise about the outside and in the flue. These gases take fire, and their combustion aids in heating the receptacle and coking the cat.

The gases gtmeratcd by the heat w ien under su'llicient iressure esca e through the sealing material; but the pro nets of combustion or the flames cannot enter into the interior of the receptacle, nor when the receptacle has been removed from the furnace and is still very hot can sutlicient oxygen enter"- into the receptacle to cause the combustion of the peat.

With a single lluc the efficiency of the device is increased and the product produced is rendered more uniform, for the heat from the furnace all'ects the center of the mass in the receptacle as well as the outside-s. If desired, the chamber may be provided with more than one hug-and for the )urpose of regulating the flow of heat through the. ilue a damper or baf ilc-platc 8 may be arranged at the top.

The invention claimed is- A coking-rcceptacle consisting of a chamber having closcd top and side walls, a iluc open at both ends extending through the top of the chamber, a base supporting the chamber, a flang extending upwardly from 2. A coking-receptacle consisting ol" chamber having a ilue extending therethrough and open at the top and button a base supi,

orting the chamber and having a trough near its periphery for receiving the lower edge of the chamber and a trough near its center for receiving the lower edge of the flue, end granular sealing material contained 1 in the troughs, substantially as specified.

A coking-receptacle consisting 0? a 15 chamber having tight top and side walls, a

ilue extending through the chamber and opening through the top, and a base having an upright flange outside of the chamber and a hollow upright hub inside of the flue, sub 20 stantially as specified.
